1. Zeotropic mixture

   A zeotropic mixture, or non-azeotropic mixture, is a mixture with liquid components that have different boiling points. For example, nitrogen, methane, ethane, propane, and isobutane constitute a zeotropic mixture. Individual substances within the mixture do not evaporate or condense at the same temperature as one substance. In other words, the mixture has a temperature glide, as the phase change occurs in a temperature range of about four to seven degrees Celsius, rather than at a constant temperature. On temperature-composition graphs, this temperature glide can be seen as the temperature difference between the bubble point and dew point. For zeotropic mixtures, the temperatures on the bubble (boiling) curve are between the individual component's boiling temperatures. When a zeotropic mixture is boiled or condensed, the composition of the liquid and the vapor changes according to the mixtures's temperature-composition diagram.Zeotropic mixtures have different characteristics in nucleate and convective boiling, as well as in the organic Rankine cycle. Because zeotropic mixtures have different properties than pure fluids or azeotropic mixtures, zeotropic mixtures have many unique applications in industry, namely in distillation, refrigeration, and cleaning processes.

1. Zeotropic mixture

   A mixture of chemicals is said to be zeotropic if the composition of the vapor and the liquid phase at the vapor-liquid equilibrium state are never the same. Dew point and bubble point curve do not touch each other over the entire composition range with the exception of the pure components. Mixtures where the both curves are touching each other in at least a single point - indicating the same composition in the vapor and liquid phase - are azeotropic mixtures. Vapor pressures and boiling temperatures of a zeotropic mixture are always between the pure component boiling points resp. vapor pressures. Azeotropic mixtures show a pressure maximum/temperature minimum or pressure minimum/temperature maximum that are above/below the values of the pure components. Stating compositions of zeotropic mixtures is common for some commercially available blends but the term zeotropic is valid only for a given temperature and pressure but not for specific compositions.
